Усилители мощности моно — Burson Audio Timekeeper Voyager

The Timekeeper Voyager is a monoblock power amplifier from Burson Audio, the Australian company known for its compact amplifiers and discrete opamps. It belongs to Burson's Voyager series and the latest of its Timekeeper amplifiers, which the company has developed for over fifteen years. It combines a Class AB output stage with high idle current and an external GaN switching power supply.

Key specs that matter

Each monoblock delivers 100 W into 8 ohms and 200 W into 4 ohms. Input impedance is 100 kohm single-ended and 200 kohm balanced. Frequency response is 20 Hz to 20 kHz, THD is below 0.03% at 1 kHz, signal-to-noise is 110 dB and output impedance is below 0.015 ohms. A switchable input buffer adds 12 dB on XLR or 6 dB on RCA. The Standard package pairs two monoblocks with a Super Charger 32 V/7 A supply at USD 5,000, and the Max package pairs them with two Fusion Core 32 V/15 A supplies at USD 6,000.

Engineering and use context

Burson deliberately runs the output stage with high idle current, drawing over 100 W at idle, so the transistors stay in their most linear region for more of the signal and crossover distortion falls. Burson describes the design as fully discrete with a Class A input buffer and a Class AB output stage. The Fusion Core supply is a GaN switching design operating at 1 MHz, placing its switching residue well beyond hearing and easing filtering, and it provides up to 480 W. Silent Power 02 regulation modules bring the regulator noise floor to 0.8 microvolts. The input buffer uses Burson's V7 Vivid Pro discrete opamps, which the owner can swap, and it can be switched in for extra gain when the source is a DAC or phone without a preamplifier, or out when a preamplifier is used. The output stage uses MOSFET transistors. The monoblock layout gives each channel its own amplifier, removing crosstalk. The Cool Case chassis dissipates heat without large heat sinks, finished in copper-gold and space grey. The mains input accepts 100 to 240 V worldwide. Burson gives a three-year warranty. Burson's range runs from the Party series through Stellar and Grand Tourer to Voyager at the top.

Pairing

Its current delivery into low impedances lets the Voyager drive speakers such as Dynaudio, B&W and KEF models. Through the buffer, a DAC with its own volume can drive it without a preamplifier.

Alternatives

Burson's Timekeeper 3X GT is the Grand Tourer series' two-channel amplifier.
